Definitions

  • the present invention relates to a pneumatic tube sleeve having a closure which has a first portion which is connectable tightly to the end of the pneumatic tube sleeve.
  • Such a pneumatic tube is eg off Fig. 2 of the EP 49347 A Scotland.
  • the closure is located with its first, cylindrical portion inside the tube post sleeve and protrudes with another section out of this. In this further section is a groove, so that the shutter can be taken automatically with appropriate grippers.
  • pneumatic mail tubes are used for the transport of blood samples. These pneumatic tubes are intended to fix the sample tubes on the one hand so that they can not break, and on the other hand they should be tight, so even in the event of a break, the blood remains within the pneumatic tube and can not pollute the piping of the pneumatic tube.
  • a pneumatic tube sleeve of the type mentioned in the present invention that this first section is connected to a second, cylindrical section of flexible foam, and that either this soft foam alone or optionally with a further flexible foam from the end of the pneumatic tube, the this closure is opposite, goes out, filling the pneumatic tube in the unfilled state completely or down to a narrow gap.
  • soft foam is meant a foam with low compression hardness, ie high point elasticity.
  • a typical example is viscose foam.
  • the distance must be less than the diameter of a typical sample tube, e.g. less than 1 cm.
  • the sample tubes can also be arranged parallel to the tube post sleeve, the soft foam gives enough and fixed the sample tubes in any position.
  • sample tubes are fixed so well by the soft foam, that in this case, they remain in constant contact and not get a short distance in order to then beat each other. Only such blows lead to breakage.
  • the closure of the invention causes both the sealing of the tube post sleeve and the fixation of the sample tube.
  • the diameter of the second section is smaller than the inner diameter of the pneumatic tube, so that a gap remains between the second section and the pneumatic tube. In this way, the soft foam does not touch the wall of the pneumatic tube, so that during insertion no friction between soft foam and wall can occur, which could otherwise lead to an undesirable deformation of the flexible foam.
  • the first portion is cylindrical and can be inserted tightly into the end of the pneumatic tube.
  • the first, cylindrical section prefferably has a projection on the side opposite the second, cylindrical section, which serves as a stop when the closure is inserted into the pneumatic tube sleeve. In this way, when closing the pneumatic tube, it is not necessary to pay attention to how deep you push the closure.
  • the first cylindrical section has two gripping holes on the side opposite the second, cylindrical section, which are arranged approximately symmetrically to the central axis.
  • the first section Cap-shaped thus essentially consists of a plate with a ring.
  • the stop or the ring is annular and the outside is corrugated or knurled or has ribs. This is especially useful with small tube diameters, where the closure can be grasped by hand at least over half the circumference.
  • first section on the side opposite the second, cylindrical section has a flat, smooth region for applying a suction cup.
  • first cylindrical portion is made of a less elastic material, such as made of solid plastic or aluminum, it is expedient if the first section has sealing lips.
  • first section has sealing lips.
  • an elastic material e.g. Hard foam
  • the closure is usually tight even without sealing lips.
  • the tube post sleeve has a pivot cover which is mounted about a pivot axis
  • the first section has a recess for the pivot axis on the side opposite the second, cylindrical section. This avoids a collision.
  • the first section has a recess for a transponder on the side facing the second, cylindrical section and / or if the second, cylindrical section has a recess for a transponder on the side facing the first section. Since the flexible foam is usually adhered to the first section, the transponder is held captive in this recess.
  • Fig. 1 an end of a pneumatic tube sleeve from the side, partly in section, which is provided only with a closure according to the invention
  • Fig. 2 one End of a pneumatic tube sleeve from the side, partly in section, which has a closure according to the invention and a conventional sleeve head with pivot cover
  • Fig. 3 a closure according to the invention from the side, partly in section
  • Fig. 4 a detail of Fig. 3 in a modified embodiment
  • Fig. 5 a closure according to the invention from above
  • Fig. 6 another embodiment of the closure according to the invention from above
  • Fig. 7 one end of a pneumatic tube sleeve from the side, partly in section, which is provided with another embodiment of a closure according to the invention
  • Fig. 8 a detail of Fig. 7 ,
  • a closure used which consists essentially of a first cylindrical portion 1 and a second cylindrical portion 2.
  • the first cylindrical portion 1 is relatively hard; it can be made of hard foam or of solid plastic.
  • the second cylindrical portion 2 should be extremely soft and therefore consists of soft foam.
  • the two cylindrical sections can be glued together or connected to each other in any other way.
  • this On the opposite side of the second section 2 of the first section 1, this has a stop 4.
  • a disk 4 ' which projects radially over the first section 1 and thus forms the stop 4.
  • This disc 4 ' may also be formed integrally with the first section 1. The stopper 4 prevents the closure can be pressed too deep into the pneumatic tube sleeve 9, which is particularly advantageous in automatic systems.
  • the closure can be used without further measures in the pneumatic tube sleeve 9, and there is a tight seal. If the elasticity of the material is not sufficient for a tight closure, sealing lips 3 may be provided on the circumference of the first section 1, as shown in FIG Fig. 4 you can see.
  • a flat, smooth area 13 is provided in the middle. At this area 13 can attach a suction cup, so that the pneumatic tube with this suction cup can be opened automatically. Especially with regard to a sufficiently large area 13, handle holes 6 are problematic with small tube diameters.
  • the first section 1 'of the closure is cap-shaped, ie it essentially consists of a plate 4' with a ring 4 "
  • the second section 2 is designed analogously as described above, ie it is cylindrical and has a gap 2 'to Sleeve tube 9.
  • the first section 1 ' may be analogous to the first section 1 described above, it may in particular also have sealing lips, on the inside of the ring 4 ", and a flat region for applying a suction cup. Due to the fact that the plate 4 'is relatively thin, it will be better in this embodiment, the recess 5 for the transponder in the second section 2, ie in the soft foam, provide.
  • the pneumatic tube sleeve 9 is formed symmetrically, that is, if it is closed at the other end as well with a closure according to the invention. But it is also possible that it is permanently closed at the other end. In this case, you can push a soft foam in the pneumatic tube sleeve 9 to the other end and leave this constantly in the pneumatic tube 9. But it is also conceivable to provide only at one end of the flexible foam, if this fills the pneumatic tube sleeve substantially entirely.
